Knife-Edged: Conquering Skye’s Inaccessible Pinnacle
A sharp little summit with big exposure — why a guided ascent is the smartest way up Skye’s most notorious spike.
The wind finds every seam. At 10 a.m. on a summer morning the Cuillin feels like a living thing: cliffs inhale sea spray and exhale cold, salt-laced gusts that rattle your jacket and sharpen your focus. You stand at the base of a slim, cathedral-like spike of jagged rock — the Inaccessible Pinnacle — and for a moment the map, the training, and the photographs fall away. It’s just you, the stone, and the hush of the Isle of Skye beyond. Guided teams call it the In Pinn; locals still say Sgùrr Dearg when they mean the ridge that shoulders it. The summit, though, is the steel tooth: a ten-meter tower that separates a Munro climb from a short, technical ascent with consequences.
Trail Wisdom
Trust the guide, train the rope skills
A short pitched climb requires basic rope handling and comfort with exposure; a brief skills session before the day makes a big difference.
Footwear matters
Choose stiff-soled approach or light mountaineering boots with good edge grip for gabbro rock.
Timing = weather window
Start early to catch the best forecasted window and avoid afternoon winds that pick up on the ridge.
Pack light, eat heavy
Bring energy-dense snacks and at least 1–1.5 L of water; wind chill increases calorie burn.

Hidden Gems
- •Explore the quieter Sligachan River pools below the Cuillin for dramatic reflections
- •Short evening scramble at nearby Sgùrr na Stri for panoramic views without the crowds

Conservation Note
Stick to established paths, avoid trampling fragile peat and heather, and follow your guide's Leave No Trace practices to protect nesting birds and delicate soils.
The Cuillin range was shaped by ancient volcanic activity and successive glaciations; its dramatic ridges have defined local crofting and maritime life for centuries.
Seasonal Guide
spring
Best for: Quieter approach trails, Snow-free low routes on warm days
Challenges: Unstable spring weather, Possible snow patches at higher elevation
Spring brings lengthening days and fewer crowds, but expect changeable weather and intermittent snow on exposed sections.
summer
Best for: Long daylight hours, Most stable weather windows
Challenges: Higher visitor numbers, Sudden rain and wind still possible
Summer is the optimal season for a guided In Pinn ascent — long days and generally more predictable conditions make ropework easier.
fall
Best for: Cool, crisp conditions, Dramatic light for photos
Challenges: Shortening days, Rapid weather shifts and early winter storms
Autumn reduces crowds and delivers spectacular colors, but check forecasts carefully as storms can arrive fast.
winter
Best for: Serious mountaineers, Mixed winter skills practice
Challenges: Extreme cold and ice, Requires full winter mountaineering gear
Winter ascents are technical and require winter crampon and ice-axe proficiency — only attempt with an experienced winter guide.
Photographer's Notes
What to Bring
Climbing harnessEssential
Needed for the exposed pitch and guided rope work.
HelmetEssential
Protects against rockfall on the ridge and during scrambling sections.
Approach shoes or light mountaineering bootsEssential
Stiff sole and good grip for gabbro rock; ankle support helps on descent.
Windproof shell and layering systemEssential
Wind and spray are common; breathable, weatherproof layers keep you comfortable.
Common Questions
Do I need prior climbing experience to attempt the Inaccessible Pinnacle?
Guided trips accept capable hillwalkers who are comfortable with exposure; prior scrambling or climbing experience is strongly recommended since the final pitch is technical.
How long is the climb and how strenuous will it be?
Expect 6–8 hours total with 8–10 km of travel and roughly 600–900 m of ascent; it’s compact but requires sustained effort and concentration on exposed sections.
What is the maximum group size?
This particular tour is offered as a private guided climb; operators typically keep groups small to manage safety during the technical pitch.
Is the summit safe in wet weather?
Gabbro holds well when dry but becomes slippery when wet; guides will cancel or alter the objective if conditions make the In Pinn unsafe.
Are ropes and technical gear provided?
Yes — reputable guides supply ropes, protection, and technical equipment; climbers usually bring personal items like harnesses and helmets if they have them.
What should I do after the climb?
Head to Portree for food and drinks — eating fresh seafood and swapping stories with your guide is the classic post-climb ritual.
What to Pack
Harness, helmet, waterproof windshell, high-energy snacks — safety, protection from wind, and fuel for sustained effort
Did You Know
The Inaccessible Pinnacle is the only true Munro summit that requires rock climbing to reach, making it unique among Britain’s 282 Munros.
Quick Travel Tips
Fly to Inverness and drive to Skye, base yourself in Portree, expect patchy cell service in the Cuillin, and book guides in advance during summer months
Local Flavor
Finish the day in Portree: try fresh seafood and a local ale at traditional pubs or sample artisan baked goods; chat with guides about Gaelic place names and crofting life to connect the climb to island culture.
Logistics Snapshot
Closest airport: Inverness (INN) or Glasgow (GLA) / Trailhead: Sligachan car park / Driving from Portree: 25–40 minutes / Cell service: patchy on the ridge / Permits: none, but guided climbs recommended
Sustainability Note
The Cuillin’s vegetation and nesting birds are sensitive — stay on established paths, pack out all waste, and avoid creating new routes or leaving gear behind.
